Add dynamic contract type templates with user customization (#33)

- Add 'execute' contract type as a built-in template in backend
- Fix API response field name mismatch (types -> contractTypes)
- Remove duplicate ContractTypeTemplate definition in api.ts
- Merge built-in types from API with user templates from localStorage
- User templates created in the Templates page now appear in contract creation
